Request Infoams OSRAMAn LED driver has been developed by austriamicrosystems AG and by LG Philips LCD. The AS3693 allows dimming of multiple segments of an LCD TV backlight for high contrast ratios and optimum picture quality. This block dimming causes only the required segments of the backlight to be on, rendering bright spots in the picture especially bright and dark parts completely black. The driver controls 16 LED channels independently via built-in pulse width modulation generators, while withstanding up to 50 V. Current is controlled with 0.5% precision. External clock and synchronizing inputs enable...See full productRelated content from Photonics MediaPRODUCTSPromoted Content March 2023 IssueHigh Intensity Back-lit BacklightsAdvanced illumination, the originator of LED lighting for machine vision inspection, is proud to announce the release of their BL2 High Intensity Back-lit Backlights, a new and improved take on...WEBINARSPhotonics.com 7/22/2021Optical Methods for Enhanced Machine Vision ImagesIt has often been said that using the right lighting and imaging can make or break a machine vision application.
